I can verify that "Mix Recall" has indeed addressed my issue. I created a template that has all necessary tracks for my instruments, as well as Aux tracks, mix busses, and FX busses. All are completely empty of any plugins (except for amp sims or virtual instruments) and saved to a mix recall named "Tracking". Then, I added all of my plugins to the tracks and busses, dialed in the settings that I know will work 90% of the time, and saved that as "Mixing". It seems to work perfectly. I can record without any weird glitches or timing issues while in "Tracking" mode. Then, once I have all of my tracks recorded, I can call up the "Mixing" mode and BAM! all of my plugins appear just as I want them, settings and all. This also allows for so many possibilities for trying different versions of compressors, eq's, delays, reverbs, etc.
Another great benefit is the issue that happens when you think you have all of your tracking complete, then you start mixing and adding tons of plugins, only to realize that you either need to punch in to re-record something, or maybe record a totally new instrument or track to add to the mix. In the past, this meant that you had to freeze tracks, disable plugins, and still have "iffy" results. Now, you just switch back to "Tracking" mode, and BAM! I love it! Way to go Sonar!
